The singularity:
This is the part of a black hole in which all the mass of the black hole has been compressed to a very small space. As a result, the Singularity has almost infinite density.
The Event Horizon: This is the part of the black hole where nothing can get out. It is usually defined as a big sphere that surrounds the black hole, and which absorbs any material including light. Some theories say that only radiation can escape this area.
The Accretion Disk: This is a disk material, which goes around the black hole, forming a spiral
If a black hole is rotating, as it spins, its mass causes the space and time to rotate around it The Photon Sphere: the photon sphere is a place in which gravity is so high that photons have to travel around the black holes´ orbit. It is the place in which light is forced to stay inside the black hole. The Schwarzschild Radius: This is the event horizon´s radius. It is the radius at which the escape velocity is equal to the speed of light.Is the event’s horizon radius. Its formula is:
Jets of Gas: In some black holes, there is such high intensity that magnetic fields are emitted perpendicular to the accretion disk. Due to this, some charged particles have to go around the black hole, because it is in a magnetic field
6.spaghettification In Astrophysics, this term refers to the effect a black hole imposes on a body or matter. The term was proposed by Stephen Hawkins in his book “A Brief History of Time”, where he compared this effect to spaghettis, saying that you are stretched, and you turn so thin that you break apart, and transform into matter. Curious facts about black holes 1.They can explote (only the smaller ones) 2.They fire Intergalactic Death Rays 3.It is not their mass, it is their size what matters 4.Black holes disort Space-Time 5.Objects appear to ‘freeze’ near a Black Hole 6.Black Holes eventually evaporate over time photos Download 0.78 Mb.
